It's very simple the law of average.............................
Basic advise.
Websites are a good thing to have. The sell you, your business and your services and products you offer.
They are like advertising in news papers and magazines in the old days and work the same way..............only one of so and so many visitors will actually be convinced to get your services. So you will have to find the ways to have as many visitors as possible in order to get the one.
Read the weekly and monthly news letters sent out by search engine companies, they offer them free and they are full of good advice. A website does not have to be the best looking one but the most effective to attract the search engines to crawl it, which in turn gets ranking up on the list. The higher a site ranks the more it will be visited. It's very simple the law of average.
